Scrieți un program C/C++ care citește de la tastatură numere naturale din intervalul [3, 100], în această ordine: n și m, apoi elementele unui tablou bidimensional cu n linii și m coloane, iar la final un număr x.

Programul afișează pe ecran mesajul DA, dacă există cel puțin un element egal cu x aflat pe conturul tabloului (format din prima linie, ultima linie, prima coloană și ultima coloană), sau mesajul NU în caz contrar.
